1 Claim.

The invention relates to a carding machine and more especially to acombined picking and carding machine.

The primary object of the invention is the provision of a machine ofthis character, wherein the same will open cotton thread in reworkedwool and. in this manner eliminating costly carbonizing processes whichis necessarily required in mill work today and also will remove thesizing from all kinds of stock, especially rayon.

Another object of the invention is the provision of a machine of thischaracter, wherein the use of a. separate picking machine is avoided inthat the picking and carding of the stock will be effected in oneoperation.

A. further object of the invention is the provision of a machine of thischaracter, wherein picking and carding will be executed on all kinds ofstock, such as hair, wool, reworkable wool, silk and vegetable matter,namely, cotton, hemp, jute, flax, rayon, et cetera, and additionallymineral matter.

A still further object of the invention is the provision of a machine ofthis character, wherein the same includes a minimum number of movingparts thus occupying the least possible floor space and assuring amaximum output.

A still further object of the invention is the provision of a machine ofthis characten'which is comparatively simple in construction, thoroughlyreliable and efficient in operation, assuring a picking and carding in.a single working of the machine, and inexpensive to manufacture andinstall.

With these and other objects in view, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawing, which discloses the preferred embodiment of the invention andpointed out in the claim hereunto appended.

In the accompanying drawing:

Figure l is a side elevation of the carding machine constructed inaccordance with the invention.

Figure 2 is an enlarged fragmentary vertical sectional view showing indetail the assembly of the carding cylinder, stock guide, guide rollerand pressure roll embodied in the machine.

Figure 3 is a fragmentary perspective View of the stock guide.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, the machine as usual comprises aframe A in which is jour naled a main carding cylinder 5 having at itsperiphery the usual card clothing or Garnett wire 6 while carried by theframe A is a feeding and presser roll 1, its journal 8 at each end beingsupported in a shiftable bearing 9. The bearing fits in a guide way IE!and acting upon this bear ing is a coiled expansion spring II suitablyheld in its working relation. to said bearing. The presser roll l at itsperiphery as shown carries a rubber covering l2 although it may beotherwise surfaced, as for example with card clothing or Garnett wire.In other words, the cylinder 5 and the roll 1 may be covered at theirperipheries with light materials or each of a composition. In thisinstance the roll '5 is covered with a rubber facing at its periphery. 1

Above the roll l is a guide roller I3 suitably journaled for the guidingof the stock M over the roll I. The stock M is supplied to the machinebetween feed rolls 55, these being suitably journaled.

Supported next to the cylinder 5 and between it and the roll I is astock guide bar IE, it having the concaved face ll next to the cylinder5 while another reversely concaved face I8 confronts the presser roll land this guide bar functions to direct the stock M and to hold the sameWorkable by the card cylinder 5. The bar It is stationary and the stockis forced past the lower edge l9 by the presser roll l which rotatesclockwise and at a speed slower than. the speed of rotation of thecylinder 5, the points of the clothing 6 of the latter being in thedirection of rotation of the same and thus a direct carding action willbe had on the stock !4 at the point of the edge I9- of the bar it andsuch stock will be picked up and have full carding action in a positivemanner during the working of the machine in that the bar It firmly holdsthe stock for direct action by the cylinder 5.

The presser roll I acted upon at each end thereof by the spring M willbe held closely against the knife edge of the stock guide between thepresser roll and the cylinder 5 and this cylinder operates by rotationin the same direction with respect to the roll l but at a greater speedor rotation than the same. The stock in the feeding thereof is carriedto the lower knife edge E9 of the bar l6 which is set the properdistance from the cylinder 5 and as the stock is forced past the bar thepoints of the clothing 6 of this cylinder co-operative with the knifeedge l9 will work upon the stock, opening up the threads,

to substantially the line of closest approach of said cylinder and roll,said bar having a concave face adjacent said roll opening graduallyoutward therefrom away from said knife edge, and means for feedingmaterial to the opening between said bar and roll, said roll mounted formovement radially with respect to said cylinder and having means forpressing it yieldingly toward said knife edge and cylinder.
